80 Years Ago: Early Vought “Corsair Mk I” fighters, of the British Royal Navy’s Fleet Air Arm fly in formation, during training for their pilots in the United States, September 1943. Planes are operating out of Naval Air Station Brunswick, Maine.
While everyone remembers the Spitfire, Hurricane, Seafire, and Sea Fury, lots of people forget the FAA picked up a whopping 2,012 Corsairs for use in World War II, actually rushing them into use as carrier birds much faster than the U.S. Navy, as the latter was thought too unsafe for flattop operations. The RN pilots had a tough respect for the “wicked-looking bastard.”
The FAA used both the Vought F4U-1 and the F4U-1A/D, type classified as Corsair Mk I and Corsair Mk II, respectively, as well as the Brewster-made F3A-1D (Corsair Mk III) and the Goodyear-produced FG-1D (Corsair Mk IV), with the Goodyear bird making up almost half of the RN’s inventory.
The Brits proved their worth on carriers, using them both in Europe (they were in on attacks against Tirpitz!) and going on to see much action against the Japanese in 1944-45.

Perhaps one of the best books on FAA Corsair jocks is The Kamikaze Hunters: Fighting for the Pacific, 1945 by Will Iredale.
Armoured Carriers has a great 20-minute take on the Corsair in British service, including interviews with a number of FAA pilots, below.
